The original post for the LED cube can be found here

While the LED cube itself is pretty much finished, I recently had a chance to add a few new features and improvements to both the code and hardware. The main hardware improvement so far is a cube-to-Cerebot adapter PCB that replaces the interconnecting cable between the processor board and cube PCB. On the software side, I implemented a custom Ethernet driver that allows a user to read and process raw Ethernet packets. Using this driver, I added a new API that allows any external computer capable of writing raw Ethernet packets to control the cube. I also wrote the corresponding Python API that runs on any Linux machine with root.
